Study on Soil Stabilization by Using Natural Fiber for Artificial Lake Liner – A Review

Abstract

Soil stabilization is an essential aspect of civil engineering, and in recent years, natural fibers have been gaining popularity as a viable alternative to synthetic materials for soil reinforcement. This study focuses on the use of natural fibers, particularly coir fiber, as lining materials for soil stabilization. Coir fiber is obtained from the outer husk of coconuts and is widely used in soil stabilization due to its unique mechanical properties, including high tensile strength, excellent biodegradability, and high moisture retention capacity. Coir fiber is particularly well suited for soil reinforcement applications in regions with high rainfall and moisture content. Compared to other natural fibers like jute, sisal, and kenaf, coir fiber exhibits superior mechanical properties such as higher tensile strength and modulus of elasticity, making it more effective in resisting soil erosion and slope instability. Moreover, coir fiber is highly resistant to microbial degradation, making it a durable material for long-term soil stabilization projects. Standard proctor test (SPT), Permeability test and California Bearing Ratio (CBR) test to find out physical properties of the stabilised soil.
